Orient model

Models often arrive on their back or side. Rotate the mesh 90° around an axis until it sits the right way up. Paint, boundaries, and selections are preserved.
Click an axis to step the model 90° around it. Click again to keep going.

The grid under the model is this plate at real size — that's how big the print actually is next to your printer's bed.

Auto-partition

Layerpaint splits the mesh into regions at sharp edges. Tune what counts as sharp and how small a region to keep.
°
Crease threshold decides which sharp edges split regions. Min region absorbs any region smaller than N faces into its neighbour. Surface change (0 = off) also splits where the surface changes direction relative to its surroundings — catches soft boundaries like a horn meeting a head that the angle alone misses. Tip: raise Crease threshold so only hard edges split, then raise Surface change to pick up the subtle ones. B toggles the line overlay.
